Front

What is the Range of ALL Cube Root Functions in interval notation?

Back

(−∞,∞)

Front

What is the y-intercept of the cubic function f(x) = -2x^3 + 3x - 21?

Back

(0, 2)

Front

What is another way to say "where a function crosses the x-axis"?

Back

all of these (x-intercept, zero, root)

Front

If f(x) = -2x^3 + 3x - 21, find f(-3).

Back

24

Front

Which of the following statements is NOT true about f(x)? The range of f(x) is [-4, 2].

Back

This statement is NOT true.

Front

What is a cubic function?

Back

A polynomial function of degree 3.

Front

What is the general form of a cubic function?

Back

f(x) = ax^3 + bx^2 + cx + d, where a ≠ 0.

Front

How many x-intercepts can a cubic function have at most?

Back

A cubic function can have at most 3 x-intercepts.

Front

What is the end behavior of a cubic function?

Back

As x approaches ±∞, f(x) approaches ±∞ depending on the leading coefficient.

Front

What does the term 'x-intercept' mean?

Back

The x-value where the function crosses the x-axis (f(x) = 0).
